Late Period & Negative Pregnancy Tests: What Could It Be?

Question
hey i am 22. I had my last regular period on 2nd feb. And i had unprotected sex on 8th feb.And i get my period every 28th day. This time its late by 10 days. And i took two pregnancy tests with proper instructions. One test i did on 5th march and the other on 11th march. Both came negative. Now i am worried whether i am pregnant. What should i do? I cant afford to go to a doctor. Please help me....

Answer
If the test is negative, you may not be pregnant.  Repeat it in 7 days.  If it is still negative, you are not pregnant.  You must be careful and not have unprotected intercourse.  You need to use a reliable form of contraception such as the pill or use condoms to prevent causing yourself unnecessary stress.
